EAST LANSING — Michigan State is preparing to hit the refresh button on its offense after bringing in long-time Ohio State offensive coordinator Jim Bollman to split the Spartans' coordinator duties with former MSU QB coach Dave Warner.

Warner will call the plays, however, meaning there will be some philosophical tweaks and an air of unpredictability in Michigan State's attack.

Warner didn't have any quick answers for what it will take to make the Spartans more proficient.

"Andrew (Maxwell) needs to play a little better, our offensive line needs to protect better, our receivers need to run better routes and catch the ball a little better and our backs need to block a little bit better,'' Warner said. "It's a full team deal.''

The Spartans return a great deal of experience on offense, but they lose two of their better playmakers in tailback Le'Veon Bell and tight end Dion Sims, both of whom declared themselves eligible for the upcoming NFL Draft.
